BrandTech Scientific Titrette - Manual (Page 36)

36
This instrument may sometimes be used with hazardous materials, operations, and equipment. It is beyond
the scope of this manual to address all of the potential safety risks associated with its use in such applica-
tions. It is the responsibility of the user of this instrument to consult and establish appropriate safety and
health practices and determine the applicability of regulatory limitations prior to use.
Safety Instructions
1. Every user must read and understand this
operating manual before operation.
2. Follow general instructions for hazard preven-
tion and safety instructions; e.g., wear protec-
tive clothing, eye protection and gloves.
3. Observe all specifications provided by reagent
manufacturers.
4. Never use the instrument in an atmosphere
with danger of explosion.
5. Use the instrument only for titrating liquids,
with strict regard to the defined limitations of
use and operating limitations. Observe operat-
ing exclusions (see page 37)! If in doubt,
contact the manufacturer or supplier.
6. Always use the instrument in such a way that
neither the user nor any other person is
endangered. Avoid splashes. Only use suitable
containers.
7. Never turn handwheels when the closure cap
is screwed on.
8. Never remove the titrating tube while the glass
cylinder is filled.
9. Reagents can accumulate in the closure cap
of the titration tube. Thus, it should be cleaned
regularly.
10. For small bottles use a bottle stand to prevent
tipping over.
11. An instrument mounted on a reagent bottle
should never be carried by the housing. Break-
age or separation of the instrument from the
reagent bottle can lead to injury.
12. Never use force on the instrument.
13. Use only original manufacturer's accessories
and spare parts. Do not attempt to make any
technical alterations. Do not dismantle the
instrument any further than is described in the
operating manual!
14. Before use check the instrument for visible
damage. If there is a sign of a potential mal-
function during operation (e.g., piston difficult
to move, sticking valves or leakage), immedi-
ately stop titrating. Consult the 'Troubleshoot-
ing' section of this manual (see page 64), and
contact the manufacturer if needed.
15. The included 1.5 V micro-batteries are not
rechargeable!
The bottle-top burette Titrette ® with an electronic digital display is used for the titration of aqueous and
non-aqueous titration media (e.g., alcoholic KOH) up to a max. concentration of 1 mol/l (see page 37 for
recommended application range). It comes with a certificate of conformity according to the metrological
requirements of DIN EN ISO 8655-3. Even tight Class A tolerances for glass burettes can be achieved by
using a high-precision measuring system.
When the instrument is properly handled, dispensed liquid will only come into contact with the follow-
ing chemically resistant materials: borosilicate glass, Al

, ETFE, PFA, FEP, PTFE, platinum-iridium; PP
(screw cap). The instrument possesses a recirculation valve as the factory default.
